I can't reproduce this crash, with any of the versions of clang I have, including the 3.8.0 version in 11.0.  Is this crash repeatable for you?  If so, please attempt to get a core dump and a back trace.
Comment 3 Hal Murray 2017-02-10 06:50:19 UTC 
I think it was caused by bad memory.

Sorry for the clutter.
